Is it?
It works with motorbikes, track cars, boats, horses and some people even drag their substitute home with them, a.k.a. as caravans.
For people like me, buying a truck and trailer to haul my 6000lb (fully loaded with food, gas, water, tools, trail-repair parts, etc) K5 Blazer anywhere from 10 to 600+ miles just so I can go offroading for a day is just out of the question. My K5 is a wonderful vehicle to drive on the road, it has excellent manners, and is extremely comfortable, especially for a truck so old with stick axles.
Buying a one ton truck, and a trailer adequate for the weight of the K5 is stupid when the truck will get no better mileage, and be no more comfortable, and be significantly more expensive then the Blazer I already have.
However, my Blazer is severely lacking in protection from livestock and wildlife on the road, the rocks and obstacles it could encounter when offroading, and from the stupid drivers who
somehow manage to miss a very large truck on the highway right next to them. (or behind them, or in front of them) Drivers who then attempt to maneuver their little crap-box so that it will occupy the same place in space and time as my truck.
A nice big bumper, front and rear, as well as rocksliders on the sides will help protect my truck from these things, and as such, body protection is very high on my shopping list.
Besides, if I hit a pedestrian with my truck, or really, any similar full-size truck, the pedestrian is screwed anyways. Any incident that they would walk away from with my truck as it is now, stock, is one that would have to happen at such a low speed, that they would walk away even if I had a big steel bumper.
The physics of the situation is just not in favor of the pedestrian who weighs at most 1/15th of my trucks 6000lb weight.
400 lbs (so a very fat american) moving at walking pace is
going to loose to a 6000 lbs truck at even 30 mph
Sorry McGuffin and everyone else who wants to outlaw bumpers like Spectre is talking about, but I just don't agree. It's a stupid idea.
